Forward-looking information and statements involve known and unknown risks and uncertainties that may cause GS actual results, performance and achievements to differ materially from those expressed or implied by the forward-looking information and statements and accordingly, undue reliance should not be placed thereon. Risks and uncertainties that may cause actual results to vary include but are not limited to the speculative nature of mineral exploration and development, including the uncertainty of reserve and resource estimates; operational and technical difficulties; the availability of suitable financing alternatives; fluctuations in commodity prices; changes to and compliance with applicable laws and regulations, including environmental laws and obtaining requisite permits; political, economic and other risks; fluctuations in foreign exchange rates; as well as other risks and uncertainties.

3 Summary 100% ownership of 2 contiguous mining concessions ( Ha) in Guerrero State near State capitol Chilpancingo de los Bravo. Property overlaps a zoned MH-IOCG system of Early Tertiary age (USGS Tract T-3). The core of the system is located north of the town of Coaxtlahuacan and is best described as a northerly plunging sediment-sill complex of Early Tertiary granitoids on the order of 1000 m thick that intrudes Middle Jurassic to Middle Cretaceous marine sediments and limestones. Copper and gold occur with magnetite in this complex as: (i) stockworks, (ii) disseminations and pods, and (iii) possibly as large scale magnetite-replaced rafts (xenoliths) of limestone (iron skarn). This area may have open-pit or underground mine potential. Peripheral parts are characterized by gold and base metal rich quartz veins and sulfide-rich carbonate-hosted replacement deposits (CRD s) with underground mine potential. Further work is recommended, including up to 4000 m of diamond drill testing, airborne geophysical surveys and geological mapping.

4 Location Centered over the historic Mochitlan MH-IOCG deposit about 30 km SE of State Capitol Chilpancingo de Los Bravo, Guerrero. Historically active mines on the Property include precious metal rich sulfide deposits Guadalupe and La Fortuna.

6 USGS probabilistic mineral resource assessment. Violin is in USGS Tract T-3, a belt of Early Tertiary porphyry deposits in southern Mexico that includes Inguarán, San Isidro, Tepal and La Verde. It is magnetiterich and sericite-poor compared to these deposits.

7 Tract T-3 also includes MH-IOCG deposits Occurrence of MH-IOCG deposits in Tract T-3 might be explained by local differences in magmatic sulfur content of the causative intrusions, where fluids exsolved from hydrous but sulfate-poor magmas precipitate the bulk of transported Fe as oxide phases, with minor (but potentially economically important) Cu ± Au-rich sulfide phases and more restricted development of late-stage acidic (sercitic) alteration styles. Violin = Mochitlán.

8 Regional Geology Located in the Mixteca Terrane, an area about 200 kilometers long and 120 kilometers wide that occurs mainly in northeastern Guerrero and southwestern Puebla States. The Mixteca Terrane is in strike-slip fault contact with Oaxaquia, and rocks of the Guerrero Composite Terrane are thrust over the Mixteca Terrane. The basement of the Mixteca Terrane consists of pre-mississipian polydeformed rocks of the Acatlán metamorphic complex. Near the Property, the Acatlán complex consists mainly of the Ordovician-Devonian Cosoltepec Formation and is overlain unconformably by: (i) Middle Jurassic Cualac Conglomerate and Tecocoyunca Formation, (ii) Early Cretaceous Zicapa and Chapolapa Formations, and (iii) Morelos Formation Limestone. These rocks are intruded by Tertiary granites and granodiorites. Map from TECTONICS, VOL. 26, TC3007, doi: /2006tc001981, 2007

9 Property Geology The oldest rocks exposed on the Property are probably middle Jurassic quartzite and slate of the Tecocoyunca Formation. These overlap about 2400 Ha in the central portion of the concession area. Northwest and southwest of the Tecocoyunca Formation, supracrustal rocks are mainly limestone, sandstone, argillite and volcaniclastic rocks, probably of the Early Cretaceous Zicapa Formation. These are intruded by granite west of Coaxtlahuacan, and by northwesterly trending quartz-feldsparbiotite porphyry dikes, sills and apophyses northeast of Coaxtlahuacan. The porphyry outcrops over a total area of about 600 Ha.

10 Coaxtlahuacan Detail Geological plan view of Coaxtlahuacan showing proposed drill holes and gold geochemistry. Cross section location is in blue. Areas with magnetite apparent on surface are mapped in black hatch. The magnetite can occur as pods and disseminations in the QFP (pink), and as replacements of limestone.

11 Coaxtlahuacan Detail Conceptual cross-section of Coaxtlahuacan showing planned drill holes. RED line with arrows represents soil geochemical anomaly for gold and copper. RED triangles are rock sample locations. BLACK HATCH = magnetite rich, bedding parallel magnetitereplacement of limestone.

12 Coaxtlahuacan Mineralization The average value of 26 rock chip-channel samples is 5797 ppm Cu and 287 ppb Au from an area about 30 m long by 20 m wide exposed in this creek-draw. Mineralization is hosted in magnetite-quartz veinlets that are oriented 245º/20º NW. Subcropping magnetite in sericite altered QFP east of the road to Coaxtlahuacan. 15 rock chip-channel samples cut across an area 10 m wide by 20 m long contain 5154 ppm Cu and 759 ppb Au.

13 Work Completed Review of reports and maps by the Servicio Geologico Mexicano Fire-assay and ICP multi-element geochemical data for 118 stream sediment samples, soil samples and 520 surface rock samples. 26 line kilometers of ground magnetic and Induced Polarization surveys of Coaxtlahuacan.

14 Gold Geochemistry in Stream Sediments Three drainages overlapping a combined area of 184 Ha contain more than 55 ppb Au west and east of Coaxtlahuacan Cu.

15 Copper Geochemistry in Stream Sediments Two drainages overlapping a combined area of 109 Ha contain more than 140 ppm Cu west and east of Coaxtlahuacan Cu. A broader > 70 ppm Cu anomaly centered on Coaxtlahuacan Cu overlaps an area of 895 Ha in 6 contiguous drainages.

16 Lead Geochemistry in Stream Sediments Three drainages over an area of 777 Ha contain more than 500 ppm Pb centered on Guadalupe and Fortuna.

17 Gold Geochemistry in Soil Samples Map of gold concentration (ppb) in soil samples. The most significant gold anomaly is centered at Coaxtlahuacan. Values higher than 32 ppb Au in soil define an area 134 Ha in size. At Espinazo, gold > 32 ppb in soil defines an area 6.6 Ha in size. At Tres Amigos, gold in soil > 32 ppb defines an area of 23.2 Ha.

18 Copper Geochemistry in Soil Samples Map of copper concentration (ppm) in soil samples. The most significant copper anomaly is centered at Coaxtlahuacan. Samples with values greater than 100 ppm Cu define an area of 81 Ha that remains open to the south. The reason the survey lines are terminated in the southerly direction there is the ground south of Coaxtlahucan is flat and used for farmland. Soil disturbance due to farming would make any results there difficult to interpret. The >100 ppm copper anomaly associated with Guadalupe is 6.6 Ha in size.

19 Lead Geochemistry in Soil Samples Map of lead concentration (ppm) in soil samples. Values > 500 ppm Pb define a semi continuous anomaly 60 Ha in size between Guadalupe and La Estrella, 17 Ha at Alas de Oro, 3.6 Ha at Coaxtlahuacan and 2.7 Ha at Espinazo.

20 Geophysical Surveys Map of the magnetic field from Pacific Geophysical with overlay of gold and copper geochemistry in rocks, chargeability anomalies (RED DOTTED LINES) and drilling plan. The magnetic anomaly correlates well to surface observations of magnetite. In this environment, the magnetite correlates well to copper and gold geochemistry, but rock outcrop is mostly limited to road cuts and creek draws. Surface geology of the chargeability anomalies marked by collars C-1 to C-4 is argillic altered QFP with subdued gold and copper values in rock and rare magnetite.
